Abstract: We report measurements of the observed cross sections for $e^+e^-\to\omega\pi^+\pi^-$, $\omega K^+K^-$, $\omega p\bar p$, $K^+K^- ho^0\pi^0$,$K^+K^- ho^+\pi^-+c.c.$, $K^{*0}K^-\pi^+\pi^0+c.c.$,$K^{*+}K^-\pi^+\pi^-+c.c.$, $\phi\pi^+\pi^-\pi^0$ and $\Lambda \bar \Lambda\pi^0$ at $\sqrt s=$ 3.773 and 3.650 GeV. Upper limits 90% C.L. are given forobserved cross sections and for $\psi3770$ decay branching fractions forproduction of these final states. These measurements are made by analyzing thedata sets of 17.3 pb$^{-1}$ collected at $\sqrt{s}=3.773$ GeV and 6.5 pb$^{-1}$collected at $\sqrt{s}=3.650$ GeV with the BES-II detector at the BEPCcollider.
